Exclusive Video

Azalea was rapping her hit song "Fancy" during a pre-VMA party at the Avalon when she lost sight of the stage and went down like the Titanic. 

It's been rough going for pre-VMA stuff.  A dancer was bit Friday by an Anaconda during a Nicki Minaj rehearsal.

As for Iggy ... security helped the 24-year old back onto the stage ... and of course, she played the whole thing off like a champ.
